Abstract
BACKGROUNDS/AIMS: Laparoscopic cholecystectomy (LC) has become widely used and preferred standard treatment for gallbladder (GB) disease in many countries. In this study, we aimed to compare the overall clinical outcomes of 3-dimensional (3D) LC system with those of the 2D LC method. METHODS: We retrospectively analyzed patients who underwent LC for acute cholecystitis between January 2010 and March 2019 at the National Medical Center in Korea. We entered them into 3D LC (group A) and 2D LC (group B) groups. We used Olympus CLV-190 laparoscopic device with dual lenses, capable of displaying both 3D and 2D images. Postoperative variables considered for evaluating between-group differences in clinical outcomes included diet resumption period after surgery, postoperative hospital length-of-stay, outpatient department follow-up period, surgical time, and postoperative surgery-related complications (blood loss and open conversion). RESULTS: We analyzed 278 acute cholecystitis patients (Group A, n=116; Group B, n=162). Compared to group B, group A had a significantly reduced surgical time and postoperative hospital stay. Although underlying diseases and abdominal surgical history were more prevalent in the 3D LC group, no significant between-group differences in blood loss and open conversion rate were observed. CONCLUSIONS: The 3D imaging system offered many advantages over 2D LC, including reduced surgical time and shorter postoperative hospital stay; therefore, it has significance in reducing hospital costs.
